Question

Alpha 1, 4, glycosidic bonds are broken when

• A. Lipid is digested by lipase
• B. Protein is digested by pepsin
• C. Starch is digested by amylase
• D. None of the above

Answer 1

The correct option is C Starch is digested by amylase

Starch is a polymeric carbohydrate made up of large number of glucose units that are joined together by glycosidic bonds.

Amylase is an enzyme that digest carbohydrates. It is secreted by the salivary gland. It acts on the alpha-1, 4-glycosidic linkages of alpha-linked polysaccharides, such as starch and glycogen to yield oligosaccharides.

Thus, the correct answer is option C.
